STONE-DRESSING MACHINE.

Specification of Letters Patent.

Patented June 25, 1907" Application filed February 15, 1907. Serial No- 357,435.

To all whom, it may concern.-

Be it known that I, WILBER H. VAN SIOKEL, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Stone-Dressing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that class of machines known as stone dressing machines in which the tool is supported so as to have a horizontal linear movement, a vertical movement and a rotary movement; In this class of machines there is generally' used a vertical standard or upright, with respect to which the tool carrying device has its movements. This standard is generally supported upon a movable base.

The object of my invention is particularly the production of a novel arrangement of this upright and its support so that the standard may readily be connected to a fixed support such, for instance, as a vertical beam and yet may readily be rotatable to enable the tool carrying device to move in the arc of a circle and also enable the tool carrying device to be guided in its vertical movement, and raised or lowered at the will of the operator.

In the drawings: Figure 1 is a side view of my improved stone dressing machine. Fig. 2 is an end view from right end Fig. 1. Fig. 3 is a detail view of up er end of standard showing construction with modified form of support for sheaves. Fig. 4 is a view simi lar to Fig. 3 showing standard supported from upper end.

a is a beam or upright having the projecting brackets, one 1). near the lower end and the other a near the upper end. The bracket 1) carries the bearing d and the bracket 0 the bearing 0.

f is a standard preferably bifurcated, as shown, having secured to its lower end the frame 9 carrying the bearing point h, which rests in the bearing d. The bearing 6 is orificed. A frame h is provided with a projection 'i which passes through and projects beyond the orifice inbearing e. The end of this projection t, beyond the bearing 6 is threaded. An orificed washer or plate j surrounds this projection i. The under surface of this plate 7' and the upper face of bearing e are grooved for a ball race. A nut 76 on the threaded end of projection & forces the plate j against the upper surface of the bearing e. Between the plate and bearing 6 are the balls Z. The lower face of frame It is bored to form a bearing 4, and in which rests the bearing point m of a frame 71 secured to the upper end of standard 0 is a yoke projecting downward from frame h, on opposite sides of standard An orifice p is formed in the standard f and the yoke 0 in which rests the trunnion or shaft 9 of the sheaves r. The orifice through the standard is larger than the trunnion or shaft q so that the sheave is supported from the bearing e, independent of the standard.

8 is a horizontal frame, upon which is mounted the rollers t of the trolley or car'- riage u from which is supported the tool w.

Thus the carriage u and tool to may move along this frame 8. At the inner end of this frame 8 is the plate 20 entering between the bifurcations of the standard f so as to be movable vertically, but be guided thereby. y is a projection from this plate carrying the sheave 2. Upon the frame is the drum 1 operated by the wheel 2. A cable or cord is secured, at one end, to the hook at the outer end of the horizontal frame 8, passes up over one of the sheaves r, then around sheave .2, then back over the other-of the sheaves r and is, at its other end, secured to drum 1. With this construction, as may be seen, the standard is guided at the top and bottom and may readily be rotated, carrying with it the horizontal frame 8 and its carried tool. Moreover the weight of the frame 8 is supported independently of the standard, enabling the turning of the standard with ease. The frame 8 is moved vertically by turning the wheel 2. p

If desired, I can carry the frame 8 upon the standardf as shown in the construction illustrated, Fig. 3. In this case the trunnion or shaft g for the sheaves r is mounted in an orifice in the standard. In this case the bearing point 5 from the frame 6 rests in a socket 7 formed in the bearing block 8, secured to the bracket 0. In this case, as in the previously described construction, the standard is supported at one end and guided at both ends, but instead of supporting the arm independent of the standard, it is supported upon the standard.

l )Instead of supporting the standard at its lower end, I can support it at the upper end as illustrated in Fig. 4. In this case the upper bracket 0 carries a hollow bearing 9 through which projects the journal 10, the frame 11 of which is secured to the standard. This journal 10 extends beyond the bearing 9 and is threaded at its upper end. An orificed plate 12 surrounds this extension of the journal 10. The lower surface of this plate 12, and the upper surface of bearing 9 is formed into a ball race 13 in which are the balls 14. A nut 15 working on the end of the extension of the bearing point 10 forces the plate 12 toward the bearing 9. In this construction the standard is guided at both ends, but is supported at the upper end, the horizontal frame being supported from the standard.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

'1. In combination, a standard rotatably supported, a frame adapted to carry the tool, rotatable with said standard and movable vertically thereon, and means to support said frame independent of the standard.
